SystemVerilog OOP Mastery · All levels
No Operator Overloading
C++ can overload operators for custom types; SystemVerilog cannot. Verification code must expose named methods like add(), equals(), compare(), and hash().
Overview
C++ can overload operators for custom types; SystemVerilog cannot. Verification code must expose named methods like add(), equals(), compare(), and hash().
Operator overloading makes domain objects feel native in C++, because expressions like a + b or lhs == rhs call user-defined methods. That can improve readability for math-like abstractions and value objects.

SV VS C++ FEATURE MATRIX
+------------------------+-------------------+------------------------+
| capability | SystemVerilog | C++ |
+------------------------+-------------------+------------------------+
| multiple inheritance | no | yes |
| interfaces as classes | interface class | abstract class idiom |
| templates | parameterized cls | templates |
| memory control | GC-like handles | manual/RAII/smart ptr |
| reflection/factory use | common in UVM | framework dependent |
+------------------------+-------------------+------------------------+
SV OOP is tuned for verification productivity over low-level control.
